Ebysus  allows the introduction of as many species as desired using DIPER format atom files and the CHIANTI database [1]}, [2]}. The number of ionized and excited levels, transitions, and rates are detailed in these atom files. The code allows one to easily perform numerical simulations with any chosen mixtures following identical numerical strategies focusing on the system of equations presented in the previous section, as long as the atom files associated with all species considered are provided. The Ebysus  code also has the possibility of running a single-fluid MHD option allowing a comparison with multi-fluid MHD models using the same numerical code.
